Dr. Joseph Dorn has had a unique vantage point when it comes to the burgeoning medical marijuana industry in Florida.

Dorn was the medical director of Surterra Therapeutics, which is one of the six dispensing organizations licensed to grow and distribute medical cannabis in the state. He resigned from that position two months ago and has opened a medical marijuana treatment center as Amendment 2 takes effect on Tuesday.

The constitutional amendment, which was approved by 71 percent of Florida voters, allows higher-strength marijuana to be used for a wider list of medical ailments. However, the true measure of what the amendment means won’t be immediately seen until a new set of rules are adopted and implemented by the Florida Legislature and the Department of Health.

“I think the expectations for most people is it is going to be a free-for-all, and all people have to do is get their cards to receive it,” Dorn said. “I think there is going to be a lot of chaos initially because there is still a lot of work to be done.”
